In IE, everything works perfectly fine. In Firefox, when you hold your mouse on one of the images you'll also see that it's printing out the id of the div that it's in (it's doing it with a document.onmouseover event). However, if you hold your mouse somewhere in the div (inside the border) but NOT on the image, it won't print out the div name.

The question... Is there ANY way for me to be able to tell which div the user has their mouse over as they're moving their mouse (not on mousedown or mouseup, because I'll need to be changing certain properties of the divs as the mouse moves over them while the mouse button is down)?
